Okay, I am making a project that should notify me via email or something to tell me when the room gets too hot. Simple eh? I thought so... But i quickly figured out I can no find a nice way to actually get the Arduino to send an email or something of the sort. . . . . I have an Ethernet Shield so do you guys have any suggestions of what i could do?

/*SEND AN EMAIL WITH ARDUINO9/23/11This code was created by modifying the connect example from arduino.cc and with the help of the YABB forums and their very helpful members.This code sends an email to any email address and then disconnects. */

Okay I (sorta) got this working right. I am using a private/work SMTP server and it usually connects fine over the internet but when i try reconnecting with the same LOCAL IP address it wont connect but if i change it, it does. THIS MAKES noooo sense to me what-so-ever...like, I can connect perfectly fine one time and then hit the reset button and it wont connect... ): please help me. When i use cmd to telnet in, it works every time. but my little arduino seems to be having issues :/

How about an SMS message? There are at least a few ways to send Tweets from an Arduino with an Ethernet shield (GIYF). Twitter can then send them to your phone. I'm using ThingSpeak and their Twitter interface to do something similar.

Yeah. but.. Now with twitter using Oauth, it's pretty much you passing your log in info and status to a server which then does the real work of posting the twitter status. Which is what i described up there... Which i'd rather not do, i mean i've got the thing to send multiple emails and it worked great! just for some reason it wont simply connect : / maybe i can try again when i'm at the office on the same local network as the SMTP server, perhaps that will stop my issue.
